Bookbinding screws allow you to bind together stacks of paper or cardboard with different thicknesses. With this method, unique sample fan decks, photo albums (e.g. a HIDDEN POST PHOTO ALBUM), menus or presentation folders can be made. The given lengths describe the possible thickness of your “book” between the two screw heads. When trying to choose the right screw length, please take into consideration that you do not want bookbinding screws that are too long because the bound sheets of paper will then tend to flap around - a 20 mm screw, for example, is the right one for a 20 to 24 mm stack; after 25 mm, a 25 mm screw must be chosen. By employing the extensions, the distance between the two screw heads can be increased by 5 and 10 mm respectively. It should be noted that the 5 mm extensions can only be used in conjunction with the shorter bookbinding screws (up to 5 mm) because the longer screw part of the longer bookbinding screws (7 mm and up) cannot be fully screwed into the short extension. Not all bookbinding screws are alike. The most important things to note are whether it is easy to screw both in and out, how well it holds the joined material together despite that ease of use; whether, after being used numerous times, it begins to change colour (i.e. the alloy fades) and, lastly, whether it is substantially made. These quality attributes are evident in our bookbinding screws because the head as well as its counterpart the shank are both made of solid brass. Such things as fading or wearing of the alloy at the visible and usually stressed areas of use cannot of course come to pass with brass (only the extensions are made of steel with brass coating). All the bookbinding screws have a diameter of 5 mm; for the purpose of drilling the appropriate holes, a 5 mm HOLLOW PUNCH is recommended. Or perhaps a HOLE DRILL or PAPER DRILL for those inclined to laziness.
